Interactive raytracingThe Caustic Series2 Ray Tracing Acceleration cards are PCIe add-in boards developed by the Caustic Professional group at Imagination Technologies. On the latest workstations, such as the HP Z620, or the Dell Precision T5600, they provide on average 3-5 times accelerated ray tracing (compared with CPU ray tracing) in popular 3D applications within Media & Entertainment and Computer Aided Design. With a Caustic Series2 card, 3D artists and designers can now have an interactive photorealistic viewport that is fully ray traced; from the earliest stages of modeling and look development. This saves the artist considerable time - reducing the number of preview renders necessary by catching potential problems with the modeling and look development of complex 3d scenes very early; before preview or final frame rendering.
